Looks like your cycle is just starting. You will get readings for ammonia for a while, then they will turn to nitrites and then to nitrates. Your cycle is finished when you have 0 ammonia, 0 nitrites and a reading of nitrates under 40ppm.

The cycle could take anywhere between a few weeks and a few months, which is why I have stated "for a while" rather than giving any guidelines on how long each stage might be.

You have a good test kit however, so if you take regular reading you will see changes in the readings in time.
